Apple is expected to announce the next yearly iteration of their desktop operating system OS X, version 10.12, at the Worldwide Developers Conference in June. Codenamed "Fuji" the next version of the Unix-based OS is planned to include a few minor interface tweaks to core system windows, but not nearly as significant as those made in past versions. The big change will be the addition of their controversial Siri to the desktop environment, bringing the digital assistant to all aspects of the Apple consumer's computing environment.
The implementation of Siri is said to differ than the one found on the iOS devices or on Apple Watch, with an icon for Siri set on the Menu Bar across the top similar to the Spotlight magnifying glass. Clicking this should activate a dark, transparent and familiar Siri interface across the top right hand corner of the screen and turning on voice control. There should be an interactive set of colourful waves to provide feedback to the user that Siri hears their commands, although the final interface is still in testing and may yet change.
Siri will also have a pane in System Preferences which should allow users to set a keyboard shortcut to activate the service. Mac OS 10.12 users will have the option to enable Siri at first startup, much like iOS and when the computer is plugged in on A/C power will respond to "Hey Siri" voice prompts without the need to activate first.
